Ratiometric multimodal chemosensors based on cubic silsesquioxanes for monitoring solvent polarity.
We report the multi-functionalized cubic silsesquioxane (POSS) as the ratiometric multimodal chemosensors for monitoring solvent polarity with fluorescence and (19)F NMR. The alteration of the dispersion state of the modified POSS by changing solvent polarity can be reflected into the orthogonal signal responses for the fluorescence and (19)F NMR. In addition, the ratiometric dual monitoring for the enzymatic reaction was performed using the POSS-based chemosensor.
